用于执行面板振动和/或选择性背光控制以减少包括多个显 示器的显示系统中的莫尔干涉的方法和系统Used to implement panel vibration and/or selective backlight control to reduce Method and system for Moire interference in a display system of a display

本申请涉及并要求于2015年10月30日提交的No.62/248,973(我方编号6468-4)在先临时美国专利申请的优先权，并通过引用将其整体结合于此。This application is related to and claims priority to prior Provisional United States Patent Application No. 62/248,973 (our Serial No. 6468-4), filed October 30, 2015, which is hereby incorporated by reference in its entirety.

技术领域technical field

本发明涉及多显示器系统(例如，包括多个显示面板的显示器)，其中至少第一和第二显示器(例如，显示面板或显示层)被布置成基本上彼此平行以便向(一个或多个)观看者显示三维(3D)特效。因此，本发明一般涉及显示器，并且更具体地涉及用于显示三维特效的显示系统和方法。面板振动(例如横向振动)和/或选择性背光控制被用于减少莫尔干涉，来改善对于观看者的图像质量。The present invention relates to multi-display systems (e.g., displays comprising multiple display panels), wherein at least a first and a second display (e.g., display panels or display layers) are arranged substantially parallel to each other so as to provide The viewer is shown three-dimensional (3D) special effects. Accordingly, the present invention relates generally to displays, and more particularly to display systems and methods for displaying three-dimensional special effects. Panel vibration (eg, lateral vibration) and/or selective backlight control are used to reduce moiré to improve image quality to the viewer.

背景技术Background technique

传统上，显示器以二维方式呈现信息。由这种显示器显示的图像是缺乏深度信息的平面图像。因为人们以三维观察世界，所以一直在努力提供能够以三维显示物体的显示器。例如，立体显示器通过显示对左眼和右眼分开显示的偏移图像来传达深度信息。当观察者观看这些平面图像时，它们在大脑中被组合以给出深度感。然而，此类系统是复杂的并且需要更高的分辨率和处理器计算能力以提供所显示对象的真实感。Displays have traditionally presented information in two dimensions. Images displayed by such displays are planar images that lack depth information. Since people view the world in three dimensions, efforts have been made to provide displays capable of displaying objects in three dimensions. For example, stereoscopic displays convey depth information by displaying offset images that are displayed separately to the left and right eyes. When a viewer looks at these flat images, they are combined in the brain to give a sense of depth. However, such systems are complex and require higher resolution and processor computing power to provide realism to displayed objects.

已经开发了包括以堆叠方式布置的多个显示屏幕的多部件显示器来显示真实深度。由于显示屏幕的物理位移，每个显示屏幕可显示其自己的图像以提供视觉深度。例如，美国专利公开No.2015/0323805和No.2016/0012630中公开了多显示器系统，其全部公开内容通过引用结合于此。Multi-component displays comprising multiple display screens arranged in a stacked fashion have been developed to display true depth. Due to the physical displacement of the display screens, each display screen can display its own image to provide visual depth. For example, multi-display systems are disclosed in US Patent Publication Nos. 2015/0323805 and 2016/0012630, the entire disclosures of which are hereby incorporated by reference.

当第一和第二显示器或显示层按照惯例在多显示器系统中彼此堆叠时，会发生不希望的莫尔干涉。莫尔干涉是在投射到观看者的视网膜上时由各层内的彩色滤光器之间的相互作用引起。例如，当绿色彩色滤光器重叠时，光线透射从而形成比较明亮的斑点。当绿色过滤器在例如红色过滤器上方时，将不会透射同样多的光线，从而形成暗区域。由于后部和前部显示器或显示层在被投射到视网膜上时具有略微不同的尺寸，因此像素将缓慢地从同相变为异相。这具有产生暗带和亮带的效果，又称为莫尔干涉。Undesirable moiré interference occurs when first and second displays or display layers are conventionally stacked on top of each other in a multi-display system. Moire interference is caused by the interaction between the color filters within the layers when projected onto the viewer's retina. For example, when green color filters overlap, light is transmitted creating brighter spots. When a green filter is over eg a red filter, it will not transmit as much light, resulting in dark areas. Since the rear and front displays or display layers have slightly different sizes when projected onto the retina, the pixels will slowly change from in-phase to out-of-phase. This has the effect of producing dark and light bands, also known as moiré interference.

已存在若干途径来移除多层显示(MLD)系统中的莫尔干涉。一些途径依赖于通过空间滤波来移除不需要的频率分量。该途径可使用漫射器类型系统或衍射类型系统来完成，该漫射器类型系统中，折射率大约1.5的元件具有随机表面扰动。在视觉美学(例如，图像看起来有多模糊；留有多少残余的莫尔条纹；对偏振的影响；以及损失等)方面这些系统的性能大大取决于系统配置。某些MLD系统单独地利用扩散光学(diffusive optics)来模糊最后部显示层。此途径存在以下限制：(a)漫射元件利用难以获得的专门的漫射器图案；(b)漫射元件位于偏振器之间并且薄膜基底和硬化基底两者必须免于任何双折射；以及(c)漫射元件需要单独的硬化组件(通常为玻璃)，这对最终显示系统而言增加了重量和费用。因此，单独使用漫射器来解决莫尔问题的MLD系统没有提供减少莫尔干涉的理想解决方案，尤其考虑到那些系统具有较小的外形尺寸。Several approaches exist to remove moiré in multi-layer display (MLD) systems. Some approaches rely on removing unwanted frequency components through spatial filtering. This approach can be accomplished using a diffuser-type system, or a diffractive-type system, in which elements with a refractive index around 1.5 have random surface perturbations. The performance of these systems in terms of visual aesthetics (eg, how blurry the image looks; how much residual moire is left; the effect on polarization; and loss, etc.) depends greatly on the system configuration. Some MLD systems solely utilize diffusive optics to obscure the final display layer. This approach suffers from the following limitations: (a) the diffusing element utilizes a specialized diffuser pattern that is difficult to obtain; (b) the diffusing element is located between polarizers and both the film substrate and the hardened substrate must be free from any birefringence; and (c) The diffusing element requires a separate hardened component (usually glass), which adds weight and expense to the final display system. Therefore, MLD systems that use diffusers alone to solve the Moiré problem do not provide an ideal solution for reducing Moire interference, especially given the small form factor of those systems.

仅依赖于漫射器来解决莫尔干涉的已有和现存方法无法提供一种在不对图像质量引入显著且有害的副作用的情况下针对莫尔条纹问题的可接受的解决方案。Existing and existing methods of resolving moiré interference that rely solely on diffusers fail to provide an acceptable solution to the moiré problem without introducing significant and detrimental side effects to image quality.

本发明的某些示例性实施例提供的解决方案使MLD系统中的莫尔干涉消失或大体消失。在本发明的某些示例性实施例中，MLD系统包括第一显示器和第二显示器。面板振动(例如横向振动)和/或选择性背光控制被用于减少莫尔干涉，来改善对于观看者的图像质量。在本发明的一个示例性实施例中，该MLD系统中的两个显示面板中的仅一个显示面板进行振动来使彩色滤光器模糊、或大体模糊，以代替单单依赖于漫射器等。这种减少莫尔干涉的技术(面板振动和/或背光控制)可以与、也可以不与其它减少莫尔干涉的技术相组合来使用，如根据本发明的各种实施例的漫射器和/或折射元件。Certain exemplary embodiments of the present invention provide solutions that make Moire interference disappear or substantially disappear in MLD systems. In some exemplary embodiments of the invention, an MLD system includes a first display and a second display. Panel vibration (eg, lateral vibration) and/or selective backlight control are used to reduce moiré to improve image quality to the viewer. In an exemplary embodiment of the invention, only one of the two display panels in the MLD system vibrates to obscure, or substantially obscure, the color filters, instead of relying solely on a diffuser or the like. Such moiré reduction techniques (panel vibration and/or backlight control) may or may not be used in combination with other moiré reduction techniques, such as diffusers and / or refraction elements.

本发明涉及多显示器系统(例如，包括多个显示面板的显示器)，其中至少第一和第二显示器(例如，显示面板或显示层)被布置成基本上彼此平行，以便向(一个或多个)观看者显示三维(3D)特效。在不同的实施例中，显示器可以是平的或弯曲的。因此，本发明的实施例通常涉及显示器，并且更具体地涉及用于显示三维特效的显示系统和方法。根据本发明的示例性实施例的MLD可被作为例如车辆仪表盘中的显示器，以(例如，为速度计、车辆仪表、车辆导航显示器等)提供3D图像。The present invention relates to multi-display systems (e.g., displays comprising multiple display panels), wherein at least a first and a second display (e.g., display panels or display layers) are arranged substantially parallel to each other so as to provide (one or more ) The viewer is shown a three-dimensional (3D) special effect. In different embodiments, the display can be flat or curved. Accordingly, embodiments of the present invention relate generally to displays, and more particularly to display systems and methods for displaying three-dimensional special effects. MLDs according to exemplary embodiments of the present invention may be used, for example, as displays in vehicle dashboards to provide 3D images (eg, for speedometers, vehicle gauges, vehicle navigation displays, etc.).

例如，由于RGB像素被排列成RGB列，两个LCD彩色滤光器阵列的图案规则性会引起彩色莫尔干涉问题。彩色莫尔干涉大多发生在水平方向上。For example, since the RGB pixels are arranged in RGB columns, the pattern regularity of the two LCD color filter arrays can cause color moire interference problems. Color moiré interference mostly occurs in the horizontal direction.

本发明的某些示例性实施例提供解决方案来使MLD系统中的莫尔干涉消失或大体消失。在本发明的某些示例性实施例中，MLD系统至少包括第一和第二显示器，该第一和第二显示器以堆叠关系来提供，以便分别位于彼此平行或大体平行的不同平面上。在本发明的某些示例性实施例中，MLD系统包括第一显示器和第二显示器。面板振动(例如，柏林噪声的引入那样的横向振动)和/或选择性背光控制被用于减少莫尔干涉，来改善对于观看者的图像质量。在本发明的一个示例性实施例中，该MLD系统中的两个显示面板中的仅一个显示面板进行振动来使彩色滤光器模糊、或大体模糊，以代替单单依赖于漫射器等。另一面板不振动。这种减少莫尔干涉的技术(面板振动和/或背光控制)可以与、也可以不与其它减少莫尔干涉的技术相组合来使用，如根据本发明的各种实施例的漫射器和/或折射元件。Certain exemplary embodiments of the present invention provide solutions to make Moire interference disappear or substantially disappear in MLD systems. In some exemplary embodiments of the present invention, the MLD system includes at least first and second displays provided in a stacked relationship so as to lie on different planes that are parallel or substantially parallel to each other, respectively. In some exemplary embodiments of the invention, an MLD system includes a first display and a second display. Panel vibrations (eg, lateral vibrations such as the introduction of Perlin noise) and/or selective backlight control are used to reduce Moire interference to improve image quality to the viewer. In an exemplary embodiment of the invention, only one of the two display panels in the MLD system vibrates to obscure, or substantially obscure, the color filters, instead of relying solely on a diffuser or the like. The other panel does not vibrate. Such moiré reduction techniques (panel vibration and/or backlight control) may or may not be used in combination with other moiré reduction techniques, such as diffusers and / or refraction elements.

需要注意的是，这里讨论的显示面板的彩色滤光器被称为红色(R)彩色滤光器/像素、绿色(G)彩色滤光器/像素和蓝色(B)彩色滤光器/像素。同样地，将红色LED、绿色LED和蓝色LED作为本文的背光中的光源来讨论。然而需要注意的是，也可以额外或替代地使用其它颜色。例如，青色和/或白色滤光器、像素以及光源也可以额外使用或代替红色、绿色和/或蓝色。It should be noted that the color filters of the display panels discussed here are referred to as red (R) color filters/pixels, green (G) color filters/pixels and blue (B) color filters/pixels. pixels. Likewise, red LEDs, green LEDs, and blue LEDs are discussed as light sources in the backlight of this article. It should be noted, however, that other colors may also be used additionally or alternatively. For example, cyan and/or white color filters, pixels and light sources may also be used in addition to or instead of red, green and/or blue colors.

图1和图2所示的MLD系统具有两个重叠并且大致平行的显示器。这里的MLD中的显示器(或显示层、或显示面板)可以是LCD、OLED等。扭曲向列型(TN)LCD可遵循相当通用的像素布局，诸如正方形，其中被分成红色、绿色和蓝色子像素水平延伸的三个部分。子像素可以在水平和垂直方向上由黑色掩模分开。在子像素的角落通常有一个方形突出来覆盖驱动晶体管。有几种不同类型的像素技术可以实现现代桌面显示器和电视所需的宽屏幕观看和时间性能。本发明的实施例与所有这些LCD兼容，因为背板被设计为遵循基本的RGB条纹像素布局。如此，每个像素所需的背板布局不需要改变，只需要改变彩色滤光掩模布局。例如，制造商提供的像素类型包括：松下(IPS Pro)、LG显示器(H-IPS&P-IPS)、瀚宇彩晶(S-IPS)、友达光电(A-MVA)、三星(AFFS)、S-LCD(S-PVA)以及夏普公司(ASV和MVA)。IPS类型LCD或其他LCD类型也可被使用。在某些实施例中，两个显示器或两个显示器层可以都是OLED，或者一个显示器可以是OLED而另一个是LCD。注意在OLED中，各子像素或像素将使用红色、绿色和蓝色材料来填充。The MLD system shown in Figures 1 and 2 has two superimposed and approximately parallel displays. The display (or display layer, or display panel) in the MLD here may be LCD, OLED or the like. Twisted Nematic (TN) LCDs may follow a fairly common pixel layout, such as a square, which is divided into three sections with red, green and blue sub-pixels extending horizontally. Sub-pixels can be separated horizontally and vertically by a black mask. There is usually a square protrusion at the corner of the subpixel to cover the drive transistor. There are several different types of pixel technologies that enable the widescreen viewing and temporal performance required by modern desktop monitors and televisions. Embodiments of the present invention are compatible with all these LCDs because the backplane is designed to follow the basic RGB striped pixel layout. In this way, the layout of the backplane required for each pixel does not need to be changed, only the layout of the color filter mask needs to be changed. For example, the types of pixels offered by manufacturers include: Panasonic (IPS Pro), LG Display (H-IPS&P-IPS), HannStar (S-IPS), AU Optronics (A-MVA), Samsung (AFFS), S-LCD (S-PVA) and Sharp Corporation (ASV and MVA). IPS type LCD or other LCD types may also be used. In some embodiments, both displays or both display layers may be OLEDs, or one display may be OLED and the other LCD. Note that in OLEDs, the individual subpixels or pixels will be filled with red, green and blue materials.

图1示出了根据本发明的示例性实施例的MLD。显示器或显示层2最接近MLD的背光源，并且优选为其背板面朝背光系统以回收可能通过行驱动器、列驱动器、晶体管和存储电容线进入背光源的光。如图所示，可使用两个偏光器的配置，并且在需要时，间隙可被设计成包括具有双折射特性的空气或材料，该空气或材料被设计成保持显示器的黑色状态。间隙可包括具有与玻璃或任一侧的层紧密匹配的折射率的材料，以减小内部反射和/或去极化效应。对于前显示器或显示层1，其背板可被定向为与显示器或显示层2的背板相反。具体而言，对于前显示器1，其背板可被定向为面向观看者以减少内部反射。因此，在图1中可以看出，各显示器1和2的彩色滤光层(其中的每一个可由一个或多个层组成)面向彼此，且在第一与第二显示器的彩色滤光层之间没有来自任一显示器的液晶层。在某些示例性实施例中，为了减少环境光的外部反射，可以提供抗反射系统，诸如由四分之一波长延迟器和抗反射偏振器构成的图1所示的抗反射系统，使得通常会被反射的环境光将在第一次通过AR偏振器时经历四分之一波长的旋转，被背板元件反射，并在通过四分之一波长延迟器时经历第二次旋转。在该环境光经过此第二次旋转时，基本上与AR偏振器的透射轴正交，因此将被基本吸收。另外，黑色掩模(BM)或其他非反射材料可被添加到显示器的导电迹线后以减少反射。另外，在本发明的某些示例性实施例中，抗反射(AR)涂层可被应用于内表面。如上所述，用于减少莫尔干涉的振动和/或选择性背光控制的使用可以避免需要在MLD系统的两个显示面板之间的间隙内提供漫射器。Fig. 1 shows an MLD according to an exemplary embodiment of the present invention. The display or display layer 2 is closest to the backlight of the MLD, and preferably has its backplane facing the backlight system to recover light that might enter the backlight through the row drivers, column drivers, transistors and storage capacitor lines. As shown, a two polarizer configuration can be used and, if desired, the gap can be designed to include air or material with birefringent properties designed to maintain the black state of the display. The gap may comprise a material with a closely matched index of refraction to the glass or layers on either side to reduce internal reflections and/or depolarization effects. For the front display or display layer 1 , its backplane may be oriented opposite to the backplane of the display or display layer 2 . In particular, for the front display 1, its backplane may be oriented to face the viewer to reduce internal reflections. Thus, it can be seen in FIG. 1 that the color filter layers of the respective displays 1 and 2 (each of which may consist of one or more layers) face each other and between the color filter layers of the first and second displays. There is no liquid crystal layer from either display in between. In certain exemplary embodiments, in order to reduce external reflections of ambient light, an anti-reflection system, such as that shown in FIG. 1 consisting of a quarter-wave retarder and an anti-reflection polarizer, may be provided such that typically Ambient light that would be reflected would undergo a quarter-wavelength rotation when first passing through the AR polarizer, be reflected by the backplate element, and undergo a second rotation when passing through the quarter-wavelength retarder. As the ambient light undergoes this second rotation, it is substantially orthogonal to the transmission axis of the AR polarizer and will therefore be substantially absorbed. Additionally, a black mask (BM) or other non-reflective material can be added behind the conductive traces of the display to reduce reflections. Additionally, in certain exemplary embodiments of the present invention, an anti-reflective (AR) coating may be applied to the interior surfaces. As mentioned above, the use of vibration and/or selective backlight control to reduce Moire interference can avoid the need to provide a diffuser in the gap between the two display panels of the MLD system.

图2是表示图1的MLD系统或其它任何具有第一和第二重叠显示面板的适合或适用的MLD系统的示意图。如图2所示，该MLD系统包括相互大体平行配置且其间具有间隙(例如空气间隙或填充有折射率匹配材料的间隙)的第一和第二显示面板。每个显示面板如上文所讨论，可以是LCD、OLED等。在后面板之后提供的背光包括多个光源(例如红色、绿色以及蓝色LED光源)，该多个光源向光导照射彩色光，该光导如图2所示将光改向到两个显示面板。图2所示的背光为边缘安装的背光，因此彩色LED光源沿着光导的边缘设置。可选地，区域阵列类型的背光可以替代地与彩色和/或白色光源一起使用。Figure 2 is a schematic diagram showing the MLD system of Figure 1 or any other suitable or applicable MLD system having first and second overlapping display panels. As shown in FIG. 2, the MLD system includes first and second display panels arranged substantially parallel to each other with a gap therebetween (eg, an air gap or a gap filled with an index-matching material). Each display panel may be an LCD, OLED, etc. as discussed above. The backlight provided behind the rear panel includes multiple light sources (eg red, green and blue LED light sources) that illuminate colored light to a light guide that redirects the light to the two display panels as shown in FIG. 2 . The backlight shown in Figure 2 is an edge-mounted backlight, so the colored LED light sources are positioned along the edge of the light guide. Optionally, an area array type of backlight may instead be used with colored and/or white light sources.

图2示出一可移动(例如可旋转)凸轮，该凸轮在被移动(如旋转)时，将面板振动(例如柏林噪声)引入后显示面板，从而使后显示面板在D方向上前后移动。该偏心凸轮例如可以绕旋转轴/轴RA旋转，来使后面板在D方向上前后移动。在本发明的各种实施例中，该凸轮可以直接或间接地接触后面板来对后面板施加这种振动。在某些示例性实施例中，可以诸如经由弹簧(未图示)向面板的与凸轮相反的一侧施加偏置力，来有效地向凸轮提供对抗使该面板移动的力。因此，应当理解的是该凸轮仅使MLD系统中的两个显示面板中的一个显示面板振动(另一个显示面板不振动)。虽然图3中示出了由电动机藉由旋转轴RA驱动的偏心旋转凸轮来作为使其中一个面板振动的振动设备，但也可以替代或额外使用其他类型的振动设备(如往复式凸轮、往复式凸锤、弹簧偏置构件等)。图3是俯视图，左侧示出使面板不振动，右侧示出使面板振动，来减少本文的任意实施例的MLD系统中的莫尔干涉。虽然图2示出被振动的是后显示面板，但本发明的可选实施例中可以代之以对前显示面板进行振动。2 shows a movable (eg, rotatable) cam that, when moved (eg, rotated), introduces panel vibrations (eg, Perlin noise) into the rear display panel, thereby moving the rear display panel back and forth in the D direction. The eccentric cam, for example, can be rotated around the rotation axis/axis RA to move the rear panel back and forth in the D direction. In various embodiments of the invention, the cam may directly or indirectly contact the rear panel to impart such vibrations to the rear panel. In some exemplary embodiments, a biasing force may be applied to the side of the panel opposite the cam, such as via a spring (not shown), to effectively provide the cam with a force against moving the panel. Therefore, it should be understood that the cam vibrates only one of the two display panels in the MLD system (the other does not vibrate). Although an eccentrically rotating cam driven by an electric motor via a rotating shaft RA is shown in FIG. 3 as a vibrating device for vibrating one of the panels, other types of vibrating devices (such as reciprocating cams, reciprocating cams, protruding hammer, spring biasing member, etc.). Figure 3 is a top view, left showing no vibration of the panel and right side showing the panel vibrating, to reduce Moire interference in the MLD system of any of the embodiments herein. Although FIG. 2 shows that it is the rear display panel that is vibrated, alternative embodiments of the present invention may instead vibrate the front display panel.

柏林噪声是可以被施加于两个显示面板的其中之一来减少莫尔干涉的振动的一个示例性类型。柏林噪声是一种梯度噪音，具有伪随机特性。在某些实施例中，柏林噪音的所有视觉细节可以是相同大小。在某些示例性实例中，可以使用柏林噪声的多个缩放副本。尽管柏林噪声是本文的某些实施例中可以使用的振动的示例性类型，但本发明并不限于此，也可以使用其它类型的振动。Perlin noise is an exemplary type of vibration that can be applied to one of the two display panels to reduce Moire interference. Perlin noise is a gradient noise with pseudorandom properties. In some embodiments, all visual details of Perlin noise may be the same size. In some illustrative examples, multiple scaled copies of Perlin noise may be used. Although Perlin noise is an exemplary type of vibration that may be used in some embodiments herein, the invention is not so limited and other types of vibration may be used.

参考图4，可以与面板振动相结合地使用选择性背光控制来减少莫尔干涉从而改善对于观看者的图像质量。图4是时序图，该时序图被使用时允许能在不施加任何额外模糊的情况下在黑色背景中维持白色像素。图4示出构成一个像素的红色(R)、绿色(G)以及蓝色(B)子像素。R、G、B子像素各自的彩色滤光器在图4中表示为平行条纹，但彩色滤光器和/或子像素也可能是其它形状。图4中的子像素可以是例如位于这里讨论的受到振动的面板中的子像素。在图4上部的最右侧三个栏中，用“0”表示背光源中一个特定的彩色LED光源被关闭，用“1”表示背光源中一个特定的彩色LED光源被打开。由此，在时间位置-1，背光中的红色LED光源关闭，且背光中的绿色和蓝色LED光源打开。作为另一实施例，在时间位置-2，背光中的红色和绿色LED光源关闭，且背光中的蓝色LED光源打开。Referring to FIG. 4, selective backlight control can be used in conjunction with panel vibration to reduce Moire interference to improve image quality to the viewer. Figure 4 is a timing diagram that was used to allow white pixels to be maintained on a black background without applying any additional blurring. FIG. 4 shows red (R), green (G), and blue (B) sub-pixels constituting one pixel. The respective color filters of the R, G, and B sub-pixels are shown as parallel stripes in FIG. 4 , but the color filters and/or sub-pixels may also have other shapes. The sub-pixels in FIG. 4 may be, for example, sub-pixels located in the vibrated panel discussed herein. In the rightmost three columns in the upper part of Fig. 4, "0" indicates that a specific colored LED light source in the backlight is turned off, and "1" indicates that a specific colored LED light source in the backlight is turned on. Thus, at time position -1, the red LED light source in the backlight is turned off, and the green and blue LED light sources in the backlight are turned on. As another example, at time position -2, the red and green LED light sources in the backlight are turned off, and the blue LED light sources in the backlight are turned on.

在图4中，例如使用绿色(G)像素或子像素来跟踪面板的位置。在时间位置0(参见位于中心的绿色像素)，背光中的R、G、B LED光源均打开。然后，当绿色像素或子像素因振动而向右移动了一个或两个子像素时(参见时间位置1和2)，背光中的红色LED光源打开，且该红色将表现为覆盖整个像素。然而，当绿色像素或子像素因振动向左移动一个或两个像素时(参见时间位置-1和-2)，背光中的红色LED光源被关闭，因此红色子像素不会表现为移动到像素的LH边界之外。这能防止(或减少)观看者看到模糊的像素。然而，出于莫尔的立场，如图4所示，当能够使红色子像素条纹(例如红色彩色滤光器像素或子像素)移动并穿过绿色和蓝色的位置，并使背光的红色部分在处于这些位置时闪烁点亮，这将使得面板在被观看者的视觉系统“融合”时出现均匀的白色。这同样适用于蓝色，只不过移动方向相反。In FIG. 4, the position of the panel is tracked using, for example, green (G) pixels or sub-pixels. At time position 0 (see green pixel in the center), the R, G, B LED sources in the backlight are all on. Then, when the green pixel or sub-pixel has moved one or two sub-pixels to the right due to vibration (see time positions 1 and 2), the red LED light source in the backlight is turned on and the red color will appear to cover the entire pixel. However, when the green pixel or subpixel is moved one or two pixels to the left due to vibration (see time positions -1 and -2), the red LED light source in the backlight is turned off, so the red subpixel does not appear to move to the pixel outside the LH boundary. This prevents (or reduces) blurry pixels from being seen by the viewer. However, from a Moiré standpoint, as shown in Figure 4, when it is possible to move a red subpixel stripe (eg, a red color filter pixel or subpixel) across the green and blue locations, and make the backlight's red The sections flash and light up when in these positions, which will cause the panel to appear uniformly white when "fused" by the viewer's visual system. The same applies to blue, but in the opposite direction.

当绿色(G)像素或子像素(对于R或B子像素也同样，因为当面板如柏林噪声那样振动时，所有子像素和像素会一起移动)因振动而向左移动一个或两个子像素时(参见时间位置-1和-2)，背光中的蓝色LED光源打开，并且蓝色将表现为覆盖整个像素。然而，当绿色像素或子像素因振动向右移动一个或两个像素时(参见时间位置1和2)，背光中的蓝色LED光源被关闭，因此蓝色子像素不会表现为移动到像素的RH(右手边)边界之外。这能防止(或减少)观看者看到模糊的像素。由此，出于莫尔的观点，如图4所示，当能够使蓝色子像素条纹(例如蓝色彩色滤光器像素或子像素)移动并穿过绿色和蓝色的位置，并使背光的蓝色部分在处于这些位置时闪烁点亮，这将使得面板在被观看者的视觉系统“融合”时出现均匀的白色。When the green (G) pixel or subpixel (same goes for the R or B subpixel, because when the panel vibrates like Perlin noise, all subpixels and pixels move together) moves one or two subpixels to the left due to vibration (see time positions -1 and -2), the blue LED light source in the backlight is turned on, and the blue color will appear to cover the entire pixel. However, when the green pixel or subpixel is moved one or two pixels to the right due to vibration (see time positions 1 and 2), the blue LED light source in the backlight is turned off, so the blue subpixel does not appear to move to the pixel outside the RH (right-hand side) boundary. This prevents (or reduces) blurry pixels from being seen by the viewer. Thus, from a Moiré point of view, as shown in FIG. The blue portion of the backlight flickers on when in these positions, which causes the panel to appear uniformly white when "fused" by the viewer's visual system.

由此可见，本发明的实施例中的MLE系统中，可以使用面板振动和/或选择性背光控制来减少莫尔干涉。It can be seen that, in the MLE system in the embodiment of the present invention, the moiré interference can be reduced by using panel vibration and/or selective backlight control.
